Allen received the technical for slamming the ball down in frustration after he was called for a loose-ball foul.
Allen's antics on the court have been well-documented this season. He was suspended by Duke for tripping opponents earlier this season.
The technical is Allen's fourth of the season, most of any ACC player. He also received a technical in Duke's last game, a 90-83 loss to rival North Carolina.
